CAR-TRUCK.

Specification of Letters Patent.

Application filed September 11, 1913.

iiatentedNov.it ,1913 Serial No. 789,331.

To all whom it may coaccm Be it known that I, l/VILLIAM F. Kinsnp, J12,a citizen of the United States, and rose dent of Altoona, county ofBlair, State of Pennsylvania, have invented certain new and usefulImprovements in Caulruchs, of which the following is a specification.

This invention relates to car trucks and more particularly to certainimprovements whereby the wear of the wheels may be compensated for tomaintain the car body at a substantially uniform height above the ail.

In prior constructions it has been customary to have a11011-t1lj11$ttbl0 connection between the journal box and the car truckand therefore the truck frame has been gradually lowered as the wheelswere or became smaller in diameter and the car body, together with thecouplers, would be likewise lowered and as a result couplers onadjoining ears have been considerably out of alinement. This is anundesirable condition in railroad practice and it has been the object ofmy invention to overcome this condition by providing means formaintaining the truck frame at a substantially uniform elevation abovethe rail as the diameter of the wheel decreased on account of wear.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a fragmentary side elevation of a truck frame and wheel;Fig. 2 is a section on the line 2-2 of Fig. l with the wheel shown inelevation; Figs. 3, t and are sections on the lines A-B of Fig. 1 andshowing different arrangements of the shims for adjusting the positionof the j ournal box with relation to the truck frame.

Referring to the drawings, 10 indicates a truck wheel which is mountedon the axle 11, the axle being provided with the journal 12 whichcarries a journal box 13. The journal box 13 is arranged between the endportions of the frame members 1 1 and 15 and as shown in the drawingsthe journal box is of less depth than the space between the framemembers 141- and 15 and the clearance space between the journal box and.the rame members is filled by means of shims.

In Figs. 1 and 3 I have illustrated two shims 16 and 17 arranged betweenthe lower side of the journal box and the lower frame member 15. This isthe arrangement of the parts when the wheel 10 is new. In

actual practice I have made the shims 16 and 17 one-half an inch thickand the car wheel has a permissible reduction in diameter of threeinches before it must be discarded. When the car wheel has worn off tosuch an extent that its diameter is reduced one inch or a reduction ofone-half an inch in the radius of the wheel, the truck frame will beone-hall. an inch nearer the rail and in order to restore the frame toits original elevatitm above the rail, one of the shims 16 or 17 istransferred to the top of the journal box 13, as shown in Fig. 1. W henthe wheel wears down another inch in diameter the truck frame is againrestored to its original height above the rail by changing the secondshim from the bottom to the top of the journal box, as shown in Fig. 5.

.Vith the parts shown in Fig. 5 the wheel is allowed to wear downanother inch in diameter so that the total reduction in diameter willamount to three inches. The wheel is then discarded.

It will be obvious, from the foregoing, that by my improved constructionit is possible to maintain the truck frame and the car body at asubstantially uniform elevation above the rail, with a maximum variationof one-half an inch where one-half inch shims are employed. If desiredfour shims, each one-quarter inch in thickness, may be employed in placeof the two one half inch shims which have been indicated on the drawingsand in this way the maximum variation in the elevation of the truckframe will not exceed onc-quarter of an inch.

In Fig. 1 it will be observed that the shims 16 and 17 are slightlycurved at one end so as to lit the radius at 18 in the truck frame.

Having described my invention what I claim and desire to secure byLetters-Patent is,

1. In a car truck, the combination with the side frame having spacedmembers be tween which the journal box is secured, of a journal box ofless depth than the space between said members, and a shim adapted tofit the top or bottom of the journal box and till the space between thebox and the frame, whereby the wear of the truck wheel may becompensated for by changing the shim from one side of the journal box tothe other.

2. In a car truck, the combination with the side frame having spacedmembers bepensated for by changing the shims from tween which thejournal box is secured, of a one side of the journal box to the other.10 journal box of less depth than the space be- In testimony whereof Iafi ix mysignature tween said members, and a plurality of in presence oftwo Witnesses.
